I am asked “What release (version) of Project do I have?” and “What is the latest update?” quite often and this is an attempt to help answer those questions.And, this also answers the question about what the differences are between a hotfix, patch, update and service pack.

Please note – always read the installation instructions on any update for software as there are pre-requisites that sometimes must be installed first or at best the update won’t work and at worst case it could stop your program from working at all.And, of course, always back up your software and data prior to patching anything!

ALSO NOTE that it is very important that the Server and Client versions of the software stay matched with updates as problems can occur if they are not equal.

To determine the version of Project that you have, open Project, go to Help and then select About.(There are other ways to determine the version, but we will only cover this one method.)

A pop-up box will appear and the top line will have the information that answers the question “What version of Project do I have?”The first part of the line will be descriptive of the version and will say something like “Microsoft Office Project Professional 2003” or “Microsoft Office Project 2007” (or 2000, 2002, 2010) as appropriate.

The next part of that line is the “File Version” or “Build” for that product.If you have installed a Service Pack then the file version or build of the Service Pack is listed as well.Here is an example:

This means that this computer is using Project 2007 with the December 15, 2009 hotfix update (found by knowing what the number “12.0.6524.5000” means) and with Service Pack 2 that has been updated with the latest Office Service Pack (that is what “12.0.6425.1000” means).

I have included a list below of the Project 2007 release numbers as of today, with the Microsoft KB article explaining the modifications:

I don’t have a full listing for Project 2003 like I provided above for 2007, but here are the original release values for Project 2003:

Office program

Release version

SP1

SP2

SP3

Project 2003

11.0.2003.816

11.1.2004.1707

11.2.2005.1801.15

11.3.2007.1529

Project 2010 and Project Server 2010 haven’t been officially released as of the writing of this article so I won’t try to put in values for those here at this time.

How do you determine what version of Project Server are you running?If you go to the Project Server itself, to the currently installed program list it will have a line for Project Server.In the 2007 version, that is called “Microsoft Office Project Server 2007”.When you select that line, there is a “Click here for support information” option.Selecting that will bring up a pop-up with the server version of the product that you are using.

As a rule, the file version of the Server should be the same as the file version on the Client.When the client says this:“Microsoft Office Project 2007 (12.0.6524.5000) SP2 MSO (12.0.6425.1000)” the Server version should also be “12.0.6425.1000” – demonstrating that they are on the same Service Pack.

Finally, here are the definitions and differences of the various update types (as taken directly from Microsoft’s TechNet Project information):

Hotfix:

A hotfix is a single cumulative package composed of one or more files used to address a problem in a product. A hotfix addresses a specific customer situation and is distributed by Microsoft Customer Service and Support. Customers may not redistribute hotfixes without written, legal consent from Microsoft.Individual hotfix releases are no longer available. Hotfixes are released to customers by Microsoft Customer Service and Support through cumulative updates.

Cumulative Update:

A Cumulative update is a method of providing hotfix releases on a scheduled delivery basis for Office Server products, including Office Project Server 2007. Through this model, Office hotfixes are released every two months in the form of a downloadable package of current and previous hotfixes. The primary goal is to deliver high-quality fixes on a predictable schedule.

Service Pack:

A service pack is a tested, cumulative set of all hotfixes, security updates, critical updates, and updates. Service packs may also contain additional fixes for problems that are found internally since the release of the product and a limited number of customer-requested design changes or features. Microsoft service packs are public updates that are available for download from the Microsoft Download Center.

Infrastructure Updates:

The Infrastructure Update for Microsoft Office Servers is a set of public updates to improve platform performance and also contains several customer-driven fixes.
